Really great product, helps our dog not pull on the lead when connecting to the front, and easy to pack into a small bag when going on trips. would definitely recommend!


So good Sadie hasnt been able to escape from this harness. 10 out 10 thank you

Best Harness on the Market by far!

Kona our 5month old Whippet prefers harnesses over collars, and yes we did try numerous collar types - martingale etc. When we switched to a harness we found Kona stopped pulling, and much happier on walks - but after a while we found the straps rubbed on long walks, we tried others in pet stores without luck and then found ‘Canine Spirit’ and Ruffwear harnesses. We went with the Flagline as it’s lightweight, x6 points of adjustment so it fits really well around Whippets chests! The handle is really helpful for getting in/out of the car, over obstacles etc.

The standout feature must be the adjustability. We sized Kona for a size that just fits (Small), little loose around the edges but after two weeks he’s filled it out and it fits perfectly. Ruffwear harnesses are absolute top quality, and I know that Kona will get years of use out of this one, because as he grows up/out/chest down we can tailor each area to fit perfectly via the x6 points of adjustment.

Compared to harnesses in general pet stores, yes Ruffwear are pricey, but... buy cheap buy twice! I’ve always been told.

Lightweight, fast drying

We also have the everyday front range harness and got this one for two reasons. Firstly, our dog loves water and the padded front range harness often ended up staying wet and nobody likes a to jump into a wet wetsuit if you know what I mean. This harness has basically no padding, just material around the straps. It dries much faster and is also much lighter. The handle is good to hold her if needed. I would only lift her if really needed on that harness as the bottom panel isn’t super wide. If you are needing to lift a larger dog (ours is 25kg) regularly, maybe look at one of the other harnesses.
Five stars for performing exactly what we need it for, attaching a long leash for recall training and playing in bigger areas or going on hikes with a longer leash.

5 star

We love our new harness.... it’s easy to put on, very light weight and durable!


This is a great harness, after buying many over the years this is by far the best.


Great fit, light weight, super easy to keep clean. Not even my husky hair sticks to it. ❤️

Gold standard for Whippets!

Love this harness! It fits my whippet like it’s tailor made. I purchased a S size for my 17kg whippet. The adjustable straps stay put and don’t slide loose with time. It’s very light, flexible and not bulky so my boy has full movement to run in it, no rubbing spots in armpits, and not too hot to wear in summer. Using the front chest attachment my boy no longer pulls on the lead - which is like magic - I would have paid double for this benefit alone. Highly recommend for whippets with all those glorious curves to fit right!

Excellent harnesses

We use these for our two staffies. Great material, easy to adjust, very secure and easy to get on and off! Love them!

Houdini no more!!

We have a very energetic 2 year old little dog, she had rolled or backed out of two different types of harness. Chatting over the fence with a lady walking her dogs, she recommended your 'Houdini' harness - we bought an XS and it has been an absolute roaring success. Fantastic to be able to walk Lily (known occasionally as Larrikin Lily) without having the worry of slipping out of her harness. Worth every cent. Will send a photo one day ( when I know how) - her tail is long and silky white (Maltese mother), poodle nose and black curls (Poodle/Dalmatian Dad), black spots Dalmatian. Quite a show stopper.

Chain Reaction Dog Collar

Replaces my old leather and slightly rusty chain collar. Fabulous easy wear, great training tool and looks super. Better than leather as it dries quickly when wet. Stylish highly recommend

Ruffwear Harness

We love our ruffwear harnesses, we even use one for our doggy guests
Awesome colours too

A comfortable and quality running or walking lead

I have used many leads for running with my dogs and this one is excellent. It’s another quality Ruff Wear product that will be my go to running lead.
